Before we apply the Time Difference of Arrival (TDOA) to locate sound target, we should have known arrival time of each sensor node at first, we present two algorithms based on the cumulative sum to estimate the arrival time. We analysis influences of location accuracy, caused by five sensors position algorithm and the distance of each node. Taking these several factors, we find the best distance between sound source and node and propose a node organizational method-retest measure method. According to the consequence of first measure, organize node to locate again. The result of simulation shows that these algorithms are in effect and the retest measure can reduce deviation effectively.
